Subject: [PATCH Part2 RFC v4 23/40] KVM: SVM: Add KVM_SEV_SNP_LAUNCH_START command
Date: Wed, 7 Jul 2021 13:35:59 -0500 [thread overview]
Message-ID: <20210707183616.5620-24-brijesh.singh@amd.com> (raw)
In-Reply-To: <20210707183616.5620-1-brijesh.singh@amd.com>
KVM_SEV_SNP_LAUNCH_START begins the launch process for an SEV-SNP guest.
The command initializes a cryptographic digest context used to construct
the measurement of the guest. If the guest is expected to be migrated,
the command also binds a migration agent (MA) to the guest.
For more information see the SEV-SNP specification.

+19. KVM_SNP_LAUNCH_START
+------------------------
+
+The KVM_SNP_LAUNCH_START command is used for creating the memory encryption
+context for the SEV-SNP guest. To create the encryption context, user must
+provide a guest policy, migration agent (if any) and guest OS visible
+workarounds value as defined SEV-SNP specification.
+
+Parameters (in): struct kvm_snp_launch_start
+
+Returns: 0 on success, -negative on error
+
+::
+
+ struct kvm_sev_snp_launch_start {
+ __u64 policy; /* Guest policy to use. */
+ __u64 ma_uaddr; /* userspace address of migration agent */
+ __u8 ma_en; /* 1 if the migtation agent is enabled */
+ __u8 imi_en; /* set IMI to 1. */
+ __u8 gosvw[16]; /* guest OS visible workarounds */
+ };
+
+See the SEV-SNP specification for further detail on the launch input.
